rl`his invention relates tol vehicle springs and' has reference more particularly to improved means for connecting the ends of a multiple-leaf spring with the vehicle frame yso as to cushion fore and aft shocks and also provide a more flexible mounting that will, .lo a certain extent, act as a shock absorber. A further object of the invention is to' elimi- 1 nate the ordinary springshackles and provide means for attaching the ends. of the spring to the frame in such manner that rattling of the pa ts will be eliminated. A further object of the invention is to provide a comparatively simple and inexpensive substitute. forthe ordinary spring shackle which will do away' with the noise that is produced by the present types of. construction and will also actas a cushion between the-spring and the frame and thereby en-l hance the riding qualities of the vehicle.

Otherl objects and vthe features of novelty l l will be apparent from the following descriptionv taken in connection with ing drawings, of which- 'Figure 1 is'a side elevation the accompany-A of a spring embodying my invention and. shown in its indicated at' 12 and at 13 I relation to vehicle;

ligt 2 'is an enlarged fragment of Fig. 1.;

the front axle and frame of a the rear end-of the spring form. of connection between the 'forward end of the spring` and the frame; A

Fig. 5 is a Fig. 3; and F Fig 6 is acsection on the line 6 6 v of ig. Referring to the dra-wings represents the front axle of l of the wheels. The frame of the vehicle is have shown a multiple-leaf spring for mounting the frame on the axle, this spring being mainly of the ordinary construction, but differing/'therefrom in the construction of its ends.

From`Fig. 1, it will be noted that there is secured to the horn 14 of theframe, by means of a pressure plate 15 .and bolts 16, a multiple-leaf scrolled spring 17, of the type commonly known as a C-shaped spring. The plates 18 and 19, of the spring 13, are

' provided at their forward end with oppo.-

- sitely turned eyes 20 and 21, respectively,

Fig. 3 is an enlarged fragment of Figfl, 3 illustrating ya modification of the con-- section on the'line 5 5. 'of' slack a motor vehicle and 11 one ing relative lateral of noise therefrom, andare securedagainst relativelateral displacement= by bolts 23.

From the foregoing description it .will be evident that the spring 17 acts as a flexible bracket and, on account of the ordinary bolt for connecting the eye of the spring with thev frame and because of the closeiitting of the intercoiled eyes, will provide a connection between the spring 13 and the frame whichisnot only capable of absorbing the fore and aft shocksz due to road conditions. but-also of verticle tieni-bility and .will and noise at this point. I

In connecting the rear end of the spring 13 with the frame' I provides. bracket 24 on the frame and mount on this bracket, b

'means of the pressure plate 25 andthe bolts formed with the loops 29 to receive the h they are The ends exterior of pins connected with the of the strap. 28 are llaidon the the spring 27 and the middle portion of the strap is formed 'with a loop 31 which is laid on the main leaf of the spring 13 and secured thereto by means of a plate 33 and a U-shaped clip 34. A plug 35 may be'arranged in the loop 31 -and by using various sizes of these plugs all or stretch in the'strap 28 may be taken up. y.

The spring 13 is provided with aneye 36 and the plate 33is likewise provided with an .e e and these eyes receive the Abolts 37, wlilc carry the side plates 38-gtor prevent- 31 andthe spring 13.

The sprin 27 is royided with eyes 31 at g p its ends and bolts 39 -in these eyes and washers 40 on thebolts prevent relative lateral displacement of the strap 28 and the spring 27.

The construction just described eliminates the usual shackle for connecting the rear end of the spring with the fframe and provides a flexible mounting for the end ofthe spring which is adapted to accommodate lengthening and shortening of the spring due has a limited amount/' eliminate wear the purpose. The 'ends of the strap 28 are 'preferably displacement of the loop noI to deiiections thereof. When the vehicle ,is in use the sp" 27 flexes under .the .i'nuenceof road shoc and thus the form of mounting which I' have' devised acts as a shockl absorber.- i In Fig. `3 I have illustrated a slight modiication of the method of connecting the strap withthe spring andthe bracket 24 and in this the .ends ofthe strap 28 are laid on the spring 13 and clamped thereto by means of the plate 41 and the clips 42.

In this form the middle portion of the strap 28 is secured between the bracket 24 and the' spring 27.

In the form of the invention illustratedin Fig. 4 the spring 17 has ends without eyes ri idly connected with the plates 18 and 19 otgthespring v31 by rivets 43, or in rany other equivalent manner.

From Fig. 1 it will be apparent that the form of the spring mountin devised rovides ample flexlbility at both ends of the spring 13; to cushionroad shocks and `also take care of any lengthening and shortening due to deflections. The'elimination of the usual spring bolts and shackles from b'oth ends of the. spring 13 provides a constructionwhich Will do away with the noise that accompanies the use of the ordilnary forms of connection and, notwithstanding the advantages possessed by my means, they may be utihzed at very cost over that of the present construction.

which I- have" little additional KHavingI thus described myinvention, what I'claim is: y

1.l In'vehicles, the combination of an axle, a frame, a multiple-leaf spring having a plurality'of eyes at one end, a scrolled-leaf spring secured intermediate its ends to said frame and having eyes with which said eyes of the multiple-leaf spring lare interengaged, and means connecting the other end of said multiple-leaf spring with the frame.

2. In vehicles, the combination of an axle, a frame, a multiple-leaf spring having a plurality of eyes at one end, a scrolled-leaf spring secured intermediate its ends to said frame and y having eyes with which said eyes of the multiple-leaf spring are interengaged, and means connecting the other end of said multiple-leat` spring with said frame adapted to accommodate the lengthenlng and shortening of the spring-due to deflections thereof.

3; In vehicles,t 1e combination of an axle, a" frame, a, multiple-leaf spring having a plurality of oppositely turned eyes at one end, a C-shaped spring secured intermediate *its ends to said frame and having eyes intercoiled With said eyes of the multiple-leaf spring. and means connecting the other end of 'said multiple-leaf spring with the frame.

In testimony 'whereof I aix my signature.
